Hi,

I recently upgraded from -STABLE at some point prior to 4.7-RELEASE
to -STABLE as it was a couple of days ago. I'm using ppp and the net/pppoa
package to connect to an ADSL line using a USB modem. This has now stopped
working in a rather odd way - and I'm guessing something has changed with
ppp, or a related tool, in -STABLE recently...

This is part of the output I get in the logfile (username removed for
privacy);

Oct 12 16:25:43 vertex ppp[207]: tun0: Phase: deflink: login -> lcp
Oct 12 16:25:53 vertex ppp[207]: tun0: Phase: bundle: Authenticate

Oct 12 16:26:12 vertex ppp[207]: tun0: Phase: Chap Output: RESPONSE
([authname])

This CHALLENGE/RESPONSE loop continues until I manually kill ppp. I'm
connecting ppp using "ppp -ddial adsl". Here is my ppp.conf (again altered
for privacy).

---start ppp.conf---
default:
 set log Phase Chat IPCP CCP tun command
 ident user-ppp VERSION (built COMPILATIONDATE)

adsl:
 set authname [authname]
 set authkey [authkey]
 set device !"/usr/local/sbin/pppoa2 -vpi 0 -vci 38 -v 1"
 accept chap
 set speed sync
 set timeout 0
 enable lqr
 set lqrperiod 5
 set redial 15 1000000
 set reconnect 15 1000000
 set dial ""
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
 add default HISADDR
 #enable dns
 nat enable yes
 nat port tcp some.internal.host:80 80
 set urgent tcp 22
---end ppp.conf---

Am I missing something obvious here?
Does anyone know what might have changed since 4.6 that might help me
isolate the problem?

To make sure it wasn't entirely something I'd bodged I then reverted the
system to RELENG_4_6, which worked fine first time.

Cheers for any help,

Tim Bishop.
